The US military has been investigating methods for improving radiographic support for field medical operations. The purpose of this project was to develop and test a portable digital radiography (DR) system to determine its feasibility for field operations. A prototype portable digital radiography device was designed and assembled using a commercially available DR sensor. The sensor and necessary hardware were mounted into a ruggedized aluminum case. The device underwent testing in the hospital and field environments. The prototype rapidly provided digital radiographs in a variety of settings. Shortcomings of the device affecting usability and reliable operation were identified. The successful construction and operation of a portable digital radiography prototype shows that such a device is feasible for field applications. The prototype requires further modification and testing to improve its usability and reliability, and to explore other potential applications, both military and civilian.

The position of the mental foramen is reported to change with age. This study aimed to examine age-related changes in the position of the mental foramen in men and women. Among 200 cases (age 21-100 years; 400 foramina) that underwent postmortem computed tomography, 109 (age 21-93 years; 218 foramina) with mandibular first and second premolars were examined using image analysis software to classify the position of the mental foramen according to Fishel's classification, and the χ² test was performed.

This study aimed to investigate the cutoff values of standardized uptake values (SUVs) and their accuracy using single-photon emission computed tomography-computed tomography (SPECT-CT) for temporomandibular joint (TMJ) osteoarthritis (OA) based on magnetic resonance imaging (MRI) and clinical examination. We included 106 joints of 53 patients with TMJ OA. SUVmax and SUVpeak of each TMJ was measured.

Many advocate adapting surgical technique based on preoperative CT staging as not all patients require complete mesocolic excision (CME) and D3 lymphadenectomy. We aimed to assess the sensitivity and specificity of preoperative CT scans in nodal staging and analyse whether inadequate CT staging could have influenced local recurrences.

Background: Veno-arterial (V-A) extracorporeal membrane oxygenation (ECMO) is commonly used for patients with cardiac arrest, cardiogenic shock, or heart failure and is a life-saving technique. Computed tomography angiography (CTA) examination in patients on ECMO presents certain challenges. Due to the dual circulation characteristics of blood flow in ECMO patients, vascular imaging and interpretation can be difficult and may even present pitfalls.

Background: Epithelioid hemangioendothelioma (EHE) is an uncommon vascular malignancy characterized by an unpredictable clinical course and a high potential for recurrence and metastasis. The lack of standard treatment guidelines, coupled with the tumor's inconsistent response to available treatments, complicates the management of EHE and leads to widely varying patient prognoses.
Case Presentation: We report two cases of EHE with distinct presentations reflecting the site of involvement.
